Abstract: The disclosure relates to a light sensor system for determining the proximity of electronic devices by analyzing the polarization of detected light. The light sensor system includes a plurality of light sensors each including polarizers, such as linear plane polarizers and/or circular polarizers. The filtered light sensors are each operable to detect light passing through the respective polarizers. The light sensor system further includes an unfiltered light sensor operable to detect the presence of light. The light sensor system includes a processor in operable communication with each of the light sensors, the processor operable to determine whether the detected light is polarized or non-polarized based on the accumulated data of the various polarized light sensors and unfiltered light sensor.
